为了使本公开的内容可以被更容易明了，以下特举实施例做为本公开确实能够据以实施的范例。另外，凡可能之处，在附图及实施方式中使用相同标号的元件/构件/步骤，是代表相同或类似部件。In order to make the content of the present disclosure more understandable, the following embodiments are specifically cited as examples that the present disclosure can be implemented. In addition, wherever possible, the elements/components/steps with the same reference numerals in the drawings and embodiments represent the same or similar parts.
图1是依照本发明的一实施例的固态硬盘的方框示意图。参考图1，固态硬盘(Solid-state drive，SSD)100包括控制电路110、固件切换电路120、第一固件存储单元130、第二固件存储单元140、固态硬盘存储单元150以及电源模组160。控制电路110耦接固件切换电路120、固态硬盘存储单元150以及电源模组160。固件切换电路120还耦接第一固件存储单元130以及第二固件存储单元140。在本实施例中，第一固件存储单元130用以存储第一固件。第二固件存储单元140用以存储第二固件。控制电路110用以依据固件切换电路120是否被触发而读取第一固件存储单元130或第二固件存储单元140，以依据第一固件或第二固件进行启动。FIG. 1 is a block diagram of a solid-state drive according to an embodiment of the present invention. Referring to FIG. 1 , a solid-state drive (SSD) 100 includes a control circuit 110, a firmware switching circuit 120, a first firmware storage unit 130, a second firmware storage unit 140, a solid-state drive storage unit 150, and a power module 160. The control circuit 110 is coupled to the firmware switching circuit 120, the solid-state drive storage unit 150, and the power module 160. The firmware switching circuit 120 is also coupled to the first firmware storage unit 130 and the second firmware storage unit 140. In this embodiment, the first firmware storage unit 130 is used to store the first firmware. The second firmware storage unit 140 is used to store the second firmware. The control circuit 110 is used to read the first firmware storage unit 130 or the second firmware storage unit 140 according to whether the firmware switching circuit 120 is triggered, so as to start according to the first firmware or the second firmware.
举例而言，第二固件存储单元140可用以存储备援固件。当固态硬盘100进行固件更新时，控制电路110可对第一固件存储单元130所存储的第一固件进行更新。然而，当控制电路110在第一固件存储单元130的固件更新结束后进行启动时，若控制电路110读取第一固件存储单元130所存储的第一固件来进行启动操作失败，则固件切换电路120将被触发。因此，当控制电路110重新启动时，控制电路110将经由被触发的固件切换电路120来读取第二固件存储单元140所存储的第二固件来进行重新启动。换言之，本实施例的固态硬盘100可有效地克服当固态硬盘100发生固件更新失败时，固态硬盘100因控制电路110无法依据更新失败的固件来进行启动操作而无法使用问题。For example, the second firmware storage unit 140 can be used to store backup firmware. When the solid-state drive 100 performs a firmware update, the control circuit 110 can update the first firmware stored in the first firmware storage unit 130. However, when the control circuit 110 is started after the firmware update of the first firmware storage unit 130 is completed, if the control circuit 110 fails to read the first firmware stored in the first firmware storage unit 130 to perform a startup operation, the firmware switching circuit 120 will be triggered. Therefore, when the control circuit 110 restarts, the control circuit 110 will read the second firmware stored in the second firmware storage unit 140 through the triggered firmware switching circuit 120 to restart. In other words, the solid-state drive 100 of this embodiment can effectively overcome the problem that when the solid-state drive 100 fails to update its firmware, the solid-state drive 100 cannot be used because the control circuit 110 cannot perform a startup operation based on the firmware that failed to update.
然而，本发明并不限于上应用范例。在其他应用范例中，第一固件存储单元130所存储的第一固件以及第二固件存储单元140所存储的第二固件可分别用以被控制电路执行而实现不同存取效能或不同节能程度。固态硬盘100的控制电路110可例如依据中央处理器(Central Processing Unit，CPU)的工作效能、电源模组160的供电状态或环境温度等因素来选择性地触发固件切换电路120，以经由固件切换电路120的触发结果来选择性地读取第一固件存储单元130所存储的第一固件或第二固件存储单元140所存储的第二固件来进行启动操作。又或者，在另其他应用范例中，第一固件存储单元130所存储的第一固件以及第二固件存储单元140所存储的第二固件可为不同固件版本，并且固态硬盘100可通过使用者以手动切换的方式来触发固件切换电路120，以使固态硬盘100的控制电路110可选择性地读取第一固件存储单元130所存储的第一固件或第二固件存储单元140所存储的第二固件来进行启动操作。However, the present invention is not limited to the above application examples. In other application examples, the first firmware stored in the first firmware storage unit 130 and the second firmware stored in the second firmware storage unit 140 can be respectively used to be executed by the control circuit to achieve different access performance or different energy saving levels. The control circuit 110 of the solid-state drive 100 can selectively trigger the firmware switching circuit 120 based on factors such as the working performance of the central processing unit (CPU), the power supply status of the power module 160, or the ambient temperature, so as to selectively read the first firmware stored in the first firmware storage unit 130 or the second firmware stored in the second firmware storage unit 140 through the trigger result of the firmware switching circuit 120 to perform a startup operation. Alternatively, in other application examples, the first firmware stored in the first firmware storage unit 130 and the second firmware stored in the second firmware storage unit 140 may be different firmware versions, and the solid-state drive 100 may trigger the firmware switching circuit 120 by manual switching by the user, so that the control circuit 110 of the solid-state drive 100 can selectively read the first firmware stored in the first firmware storage unit 130 or the second firmware stored in the second firmware storage unit 140 to perform a startup operation.
图2是依照本发明的一实施例的启动方法的流程图。参考图1以及图2，本实施例的启动方法可至少适用于图1的固态硬盘100。在步骤S210中，控制电路110依据固件切换电路120是否被触发而读取第一固件存储单元130所存储的第一固件或第二固件存储单元140所存储第二固件。在步骤S220中，控制电路110依据第一固件或第二固件进行启动。因此，本实施例的启动方法，可使固态硬盘100能有效地进行控制电路110的启动操作。另外，关于本实施例的固态硬盘100的其他装置特征、实施范例以及技术细节可参考上述图1实施例的说明而获致足够的启示、建议以及实施说明，因此在此不再赘述。FIG. 2 is a flow chart of a startup method according to an embodiment of the present invention. Referring to FIG. 1 and FIG. 2 , the startup method of the present embodiment can be at least applicable to the solid-state drive 100 of FIG. 1 . In step S210, the control circuit 110 reads the first firmware stored in the first firmware storage unit 130 or the second firmware stored in the second firmware storage unit 140 according to whether the firmware switching circuit 120 is triggered. In step S220, the control circuit 110 is started according to the first firmware or the second firmware. Therefore, the startup method of the present embodiment enables the solid-state drive 100 to effectively perform the startup operation of the control circuit 110. In addition, other device features, implementation examples and technical details of the solid-state drive 100 of the present embodiment can refer to the description of the embodiment of FIG. 1 above to obtain sufficient inspiration, suggestions and implementation instructions, so they are not repeated here.
图3是依照本发明的一实施例的切换线路的线路示意图。参考图3，本发明的固态硬盘的切换线路可如图3所示。控制电路310的多个引脚可经由线路311～313电性连接固件切换电路320，其中所述多个引脚可包括芯片选择引脚(Chip Selection，CS)、写入保护引脚(Write Protection，WP)以及保持引脚(Hold)。固件切换电路320分别经由线路321～323以及线路324～326来分别将控制电路310的上述多个引脚切换以耦接至第一固件存储单元330或第二固件存储单元340。值得注意的是，本实施例的控制电路310与固件切换电路320之间可电性连接一条额外的走线301。当控制电路310发生如上述举例说明的范例或其他情况时，控制电路310可通过走线301来提供触发信号至固件切换电路320，以触发固件切换电路320。FIG. 3 is a schematic diagram of a switching circuit according to an embodiment of the present invention. Referring to FIG. 3 , the switching circuit of the solid state drive of the present invention may be shown in FIG. Multiple pins of the control circuit 310 may be electrically connected to the firmware switching circuit 320 via lines 311 to 313, wherein the multiple pins may include a chip selection pin (Chip Selection, CS), a write protection pin (Write Protection, WP) and a hold pin (Hold). The firmware switching circuit 320 switches the above-mentioned multiple pins of the control circuit 310 to couple to the first firmware storage unit 330 or the second firmware storage unit 340 via lines 321 to 323 and lines 324 to 326, respectively. It is worth noting that an additional wiring 301 may be electrically connected between the control circuit 310 and the firmware switching circuit 320 of this embodiment. When the control circuit 310 occurs in the example described above or other situations, the control circuit 310 may provide a trigger signal to the firmware switching circuit 320 via the wiring 301 to trigger the firmware switching circuit 320.
换言之，在固件切换电路320被触发前，控制电路310是通过固件切换电路320来存取第一固件存储单元330所存储的第一固件。并且，在固件切换电路320被触发后，控制电路310是通过固件切换电路320来存取第二固件存储单元340所存储的第二固件。然而，固件切换电路320并不限于由走线301来接收由控制电路310的触发信号。在另一实施例中，固件切换电路320亦可通过另一额外的走线来连接至供使用者手动触发的触发单元，以接收由使用者触发所产生的另一触发信号，来决定控制电路310的存取对象。In other words, before the firmware switching circuit 320 is triggered, the control circuit 310 accesses the first firmware stored in the first firmware storage unit 330 through the firmware switching circuit 320. And, after the firmware switching circuit 320 is triggered, the control circuit 310 accesses the second firmware stored in the second firmware storage unit 340 through the firmware switching circuit 320. However, the firmware switching circuit 320 is not limited to receiving the trigger signal from the control circuit 310 through the wiring 301. In another embodiment, the firmware switching circuit 320 can also be connected to a trigger unit for manual triggering by a user through another additional wiring to receive another trigger signal generated by the user trigger to determine the access object of the control circuit 310.
图4是依照本发明的另一实施例的启动方法的流程图。参考图1以及图4，本实施例的启动方法可至少适用于图1的固态硬盘100。在步骤S410，控制电路110进行启动操作。控制电路110判断固件切换电路120是否被触发。若否，则固态硬盘100执行步骤S430。在步骤S430，控制电路110通过固件切换电路120读取第一固件存储单元130所存储的第一固件。控制电路110执行所述第一固件，以进行启动操作。在步骤S450，控制电路110判断是否成功启动。若是，则固态硬盘100执行步骤S470。在步骤S470，控制电路110结束启动操作。然而，若否，则固态硬盘100执行步骤S460。FIG. 4 is a flow chart of a startup method according to another embodiment of the present invention. Referring to FIG. 1 and FIG. 4 , the startup method of this embodiment can be applied to at least the solid-state drive 100 of FIG. 1 . In step S410, the control circuit 110 performs a startup operation. The control circuit 110 determines whether the firmware switching circuit 120 is triggered. If not, the solid-state drive 100 executes step S430. In step S430, the control circuit 110 reads the first firmware stored in the first firmware storage unit 130 through the firmware switching circuit 120. The control circuit 110 executes the first firmware to perform a startup operation. In step S450, the control circuit 110 determines whether the startup is successful. If so, the solid-state drive 100 executes step S470. In step S470, the control circuit 110 ends the startup operation. However, if not, the solid-state drive 100 executes step S460.
在步骤S460，控制电路110触发固件切换电路120。接着，控制电路110重新执行步骤S410，以进行重新启动。当控制电路110再次步骤S420时，由于控制电路110判断固件切换电路120被触发，因此控制电路110执行步骤S440。在步骤S440，控制电路110通过固件切换电路120读取第二固件存储单元140所存储的第二固件。控制电路110执行所述第二固件，以重新进行启动操作，并且控制电路110继续执行步骤S450及步骤S470。因此，本实施例的启动方法，可使固态硬盘100能有效地进行控制电路110的启动操作。另外，关于本实施例的固态硬盘100的其他装置特征、实施范例以及技术细节可参考上述图1实施例的说明而获致足够的启示、建议以及实施说明，因此在此不再赘述。In step S460, the control circuit 110 triggers the firmware switching circuit 120. Then, the control circuit 110 re-executes step S410 to restart. When the control circuit 110 again executes step S420, since the control circuit 110 determines that the firmware switching circuit 120 is triggered, the control circuit 110 executes step S440. In step S440, the control circuit 110 reads the second firmware stored in the second firmware storage unit 140 through the firmware switching circuit 120. The control circuit 110 executes the second firmware to restart the startup operation, and the control circuit 110 continues to execute steps S450 and S470. Therefore, the startup method of this embodiment can enable the solid state drive 100 to effectively perform the startup operation of the control circuit 110. In addition, other device features, implementation examples and technical details of the solid state drive 100 of this embodiment can refer to the description of the embodiment of FIG. 1 above to obtain sufficient inspiration, suggestions and implementation instructions, so they are not repeated here.
综上所述，本发明的固态硬盘以及启动方法，可通过两个固件存储单元来存储两个固件，并且在控制电路与两个固件存储单元之间设置有固件切换电路，以依据固件切换电路是否被触发来决定控制电路从所述两个固件存储单元的其中的一来存取固态硬盘的固件。并且，固件切换电路的触发方式可为自动或手动。据此，本发明的固态硬盘以及启动方法，可提供能够读取到有效的固态硬盘的固件来进行启动的技术效果，或可提供能够选择性读取特定固件来进行特殊启动的技术效果。In summary, the solid-state hard disk and the boot method of the present invention can store two firmwares through two firmware storage units, and a firmware switching circuit is provided between the control circuit and the two firmware storage units to determine whether the control circuit accesses the firmware of the solid-state hard disk from one of the two firmware storage units according to whether the firmware switching circuit is triggered. In addition, the triggering method of the firmware switching circuit can be automatic or manual. Accordingly, the solid-state hard disk and the boot method of the present invention can provide a technical effect of being able to read the valid firmware of the solid-state hard disk for booting, or can provide a technical effect of being able to selectively read specific firmware for special booting.
